Symmetrical/Asymmetrical Winding Reconfiguration in Multiphase Machines
IEEE Access, 2020 This paper investigates multiphase drives in which winding configuration (symmetrical or asymmetrical) can be easily obtained by only rearranging voltage source inverter (VSI) power supply cables at the machine's terminal box.

Optical Manipulation of Multiferroic Phases in BiFeO3 Thin Films
Advanced Materials Interfaces, EarlyView.At the strain‐driven morphotropic phase boundary, optical control over the multiferroic rhombohedral and tetragonal phase mixture is demonstrated using above‐bandgap light illumination. The photoinduced charge carriers modify the electrostatic environment and induce the conversion into a single tetragonal phase.

Field-Oriented Control of Multiphase Drives With Passive Fault Tolerance
IEEE Transactions on Industrial Electronics, 2020 Multiphase machines provide continuous operation of the drive with no additional hardware in the event of one or more open-phase faults. This faulttolerant capability is highly appreciated by industry for security and economic reasons. However, the steadystate post-fault operation has only been feasible in previous works after the fault localization ...

Fault Tolerance in Direct Torque Control with Virtual Voltage Vectors
Revista Iberoamericana de Automática e Informática Industrial RIAI, 2019 Reliability is considered a fundamental requirement of some variable-speed electric drives. Therefore, multiphase systems, which introduce a higher fault tolerance than conventional three-phase ones, turn out to be an interesting alternative for these ...

On the Origins of Toughness in Corymbia calophylla (Marri Tree) Nuts
Advanced Science, EarlyView.We uncover the natural toughening mechanisms of the marri nut, including fiber pullout, crack deflection, and a viscoelastic matrix, which enable exceptional energy absorption and ductility comparable to Teflon, with an elastic modulus similar to acrylic.
